Porsha calculates the amount of money she will have at the end of 6 years on a $5,000 investment earning 3.75% interest compound
OLEGan [10]
Porsha` s expression:
5,000 ( 1 + 0.0375 ) ^24
A = P * ( 1 + i  ) ^n
n = 6 * 4 = 24
i = 0.0375 : 4 = 0.009375
Porsha`s expression is wrong. True expression is:
5,000 * ( 1 + 0.009375 ) ^24
Answer: B ) Porsha`s expression should have 1 + 0.009375 in the parentheses.

Look at the image below. What is the area of the triangle? units​
Mrrafil [7]

Answer:

7 Units^2

Step-by-step explanation:

If we add an exact copy of the triangle, we can make a parallelogram.

Then we can use the parallelogram's area to figure out the triangle's area.

Hint #22 / 4

The original triangle has \dfrac{1}{2}

2

1

​

start fraction, 1, divided by, 2, end fraction the area of the parallelogram we just made.

Hint #33 / 4

\begin{aligned} \text{Area of parallelogram} &= \text{base} \times \text{height}\\\\ \text{Area of triangle} &= \dfrac{1}{2} \times \text{base} \times \text{height}\\\\ &= \dfrac{1}{2} \times 7 \times 2\\\\ &= \dfrac{1}{2} \times 2 \times 7\\\\ &= 1 \times 7\\\\ &= 7 \end{aligned}

Area of parallelogram

=1×7

=7
